CARL E. SKOOG, OF CRANSTON, RHODE ISLAND, ASSIGNOR TO D. M. WATKINS COMPANY, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OEBHODE ISLAND BUTTON Application filed October 14, 1931. Serial No. 568,722.

My invention relates to separable buttons or emblems, and more particularly to the type wherein the base carries an independently rotary fabric engaging disk.

An essential object of my invention is to prevent accidental clogging of the serrated rotary disk whereby the material of the garment is cut or abraded during the rotation of the disk carrying base.

Further objects of my invention are facility of manipulation, security, strength, and inexpensiveness of construction.

To the above ends essentially my invention consists in such parts and in such combinations ot parts as fall within the scope of the .appended claims.

In the accompanying drawings which form a part of this specification,

Figure 1 is a side elevation of my button,

Figure 2a similar view of the same partly in diametrical section,

Figure 3, a section taken on line 3-3 of Figure 1, and

Figure 4:, a fragmentary side elevation of the rotary toothed member, partly in diametrical section.

Like reference characters indicate like parts throughout the views.

The front or entrant member 6 ot my button comprises any usual or prelerred ornamental face plate or head 7 and shank or post 8 having a thread 9.

The corresponding receiving or back member 12 of the button includes a circular back plate 13 comprising a llat margin 14 and a central ilat hollow boss 15 forming an internal recess 16. The boss has a central opening 17 bounded by an internal neck or sleeve 18 provided with an internal thread 19 adapted'to engage the thread 9 of the post. A peripheral bead or flange 21 upon the back plate margin 14 snugly engages a circular base plate 22 having a central circular opening 23 concentric with the sleeve 18 whereby the plate is spaced from the latter.

A circular rotatable disk 25 rests against the front of the base plate 22. At its central portion the material of the disk is turned rearwardly to form a hub 27, loose in the opening 23, and a lateral forwardly directed annular retaining flange 29 upon the rear end of the hub loosely engaging the rear face of the plate`22 in the recess 1G. vUpon the periphery of the disk is a forwardly directed peripheral flange `30 provided with similarly directed teeth or serrations 31.

The described separable button is applied in the usual manner. f To engage the button with a coat lapel, first the head member 6 is inserted rearwardly through the button hole and there held stationary with one hand, and then with the other hand the operator grasps the bead 21 and rotates the same with its engaged plate 22 whereby the threaded sleeve 18 advances upon the post 8. During this rotation, however, when the teeth 31 in their advance contact with the lapel they merely penetrate the latter and are not circularly moved during the continued rotation of the plates 18 and 22 thereby preventing cutting or abrading.

I claim:`

1. In a button, a face plate, a rearwardly directed post provided with a screw thread, a back plate, a forwardly directed sleeve upon the back plate provided with a thread engageable with the lirst thread, a base plate tast to the back plate provided with a central opening concentric with the sleeve, a rotatable disk loose upon the base plate, and a torwadly directed serrated flange upon the dis 2. In a button, a face plate, a rearwardly directed post provided with a screw thread, a back plate, a forwardly directed sleeve upon the back plate provided with a thread engageable with the first thread, a base plate fast to the back plate provided with a central opening concentric with the sleeve, a rotatable disk slidably engaging the front of the base plate, a hub upon the disk eX- tending loosely through the opening, a retaining ilange upon the hub loosely engaging the back ot the base plate, and a forwardly directed serrated flange upon the disk.

3. In a button, a face plate, a rearwardly directed post provided with a screw thread, a back plate provided with an internal recess, a centrally disposed sleeve upon the n back plate extending into the recess and prolc ausy vided with a screw threadengagealole with the first thread, a base plate provided with a central opening concentric with the sleeve, a peripheral bead on the back'plate engaging the base plate, a disk loose on the front of the base plate, a hub upon the'disk surrounding the sleeve, a lateral forwardlyrdireoted annular retaining flange upon the huh within the recess loosely engageable with the base plate, a Vforwardly directed peripheral flange upon the disk, and teeth upon the last `mentioned flange. f

4. In a button, a face plate, a rearwardly directed post provided kwith a screw thread, a back plate, a forwardly directed sleeve upon the back plate provided with a thread engageable with the first thread, a rotatable diskV supported by thehack Yplate and .normally loose thereon, and an engaging flange upon the disk.

In testimony whereof I have allixed my signature.
